The 'Voice' USA mentor, who finalised his divorce from the country music star in July just hours after announcing the end of their four-year marriage, feels positive again and is ready to move on with his life.
A source close to the 39-year-old singer said: ''Clearly he was upset during the breakup, but he's not someone to sit around and lick his wounds. He's about moving forward and not looking in the rearview mirror.
''He experiences all the same ups and downs as anyone else, but he is doing so well and is always the life of the party.''
Blake has lost approximately 20 pounds since the split and is also focusing on writing new music.
The insider told PEOPLE magazine: ''There's been a silver lining for Blake. He has the time to take care of himself and he's taken positive steps in his life to spend time with friends and family.''
Blake and newly-single Gwen Stefani, 45, recently sparked rumours of a romance on the set of the NBC singing competition, but the insider said: ''There's nothing there. They're nothing more than friends.''
Meanwhile, Miranda has ''never felt more inspired'' after moving from the ranch she once shared with Blake in Oklahoma to Nashville.
Speaking at her Music City Walk of Fame Induction Ceremony on Tuesday (06.10.15), she added: ''I feel like a bigger part of Nashville than I ever have. I've been spending a lot of time here the last three or four months. I moved back here. I've never felt more at home.''
